...Explain the fire principals of wildland fires. And how their behavior differs from structure fires. The basic fire principals consist of five principals that go into fire behavior. Principal one is the fire triangle or Tetrahedron. The fire triangle consists of having heat, fuel, and oxygen. Removing one of these elements from the triangle and the fire will eventually die out. Principal two is method of heat transfer. Therefore, if heat is transfer from direct contact, liquid or air. A fire of some sort could arise. Methods such as convection, conduction, and radiation. Which is known to be the number one cause of any fire exposure. Principal three in stages and fire growth. This talks about the stages of a fires lowest point of ignition...

...ether, Methyl alcohol, Acetone. 9. Combustible Metals (provide examples): a metal that will combust under heat. Some examples are: Calcium, Magnesium, Sodium. 10. Carboxyhemoglobin: A compound found in the blood by binding carbon monoxide and hemoglobin. 11. Chemical Energy (provide examples of the two types): Energy stored in the bonds of chemical compounds released or taken in during exothermic and endothermic reactions. An example of an exothermic reaction is a fire burning. An example of an endothermic reaction is photosynthesis. 12. Concentration: the relative amount of a given substance contained within a solution or in a particular volume of space. 13. BTU: British thermal unit which is a traditional work equal to 1055 joules. 14. Joule: the SI unit of Work or Energy. 15. Fire: Combustion or burning in which substances combined chemically with oxygen in the air and typically give out bright light heat and smoke. 16. Fire Point: The lowest temperature at which a substance can continue to burn. 17. Fire Tetrahedron: A four-sided geometric...

...Although a quick response and quick knock down kept a Saturday evening barn fire from spreading to a nearby house, it wasn’t enough to save the barn and two horses that perished inside it. Firefighters were dispatched to 8000 County Road 189, owned and occupied by Reuben D. and Sarah H. Miller, after a resident of nearby County Road 192 reported the fire at 6:09 p.m. Prairie Township Fire Chief Reuben Miller responded straight from home. Holmes County Sheriff's Deputy Josh Summers, also a member of the fire department, responded from where he was patrolling just north of Holmesville. They arrived at 6:13 p.m., followed two minutes later by an engine from Prairie Township, said the chief, who is no relation to the owner of the property. On arrival, the...

...span of a decade. Situations have become more severe in nature and, as a result, have called for more drastic actions. Fire fighters lay down their life for others every day and ask for nothing.. With a job that receives little credibility and does not pay nearly as much as it should, the benefits of such a life-threatening career do not seem remotely close to being worth the strenuous amount of effort that it requires. Though some may choose to deny it, firefighting has now become one of the most dangerous occupations out there. Dangers with the career field of Fire Science start with the applying and regulating of rules and codes. A prime example is OSHA’s...

...SUTRA 11 Now we are going to discuss smriti, which basically means memory. The sutra says anubhuta vishaya asampramoshah smritih. Anubhuta is the first wor, and anubhuta is translated as experienced. Experience in Sanskrit is called anubhuti, so anubhuta is called experienced, an experience that you have already experienced. Anu means something that follows or follows upon and bhuta means the element. So anubhuta means that which follows the matter field when consciousness or your personal awareness interacts with the matter field and is the tangible experience. Experience is a result of consciousness interacting with the matter fields, and that is anubhuta. Vishaya is an object of the experience that you have, so in general, they are the five matter fields, but they can also be another pattern of intelligence. One samskara can even have another samskara as its object of experience. Like the drink that I am consuming is a pattern of intelligence, and the personality that’s trying to enjoy it is also a pattern of intelligence. So when you interact with an object, an experience is created out of it. If you dissect everything and look into it, you will find just five matter fields interacting with five matter fields but in reality there are just two different patterns of intelligence interacting with each other, not necessarily just five matter fields. . Asampramoshah means kept inside, not letting go or allowing to escape. That is called smritih, memory. ...

...The word fire is defined by webster as the phenomenon of combustion manifested in light, flame, and heat. What this definiton does not tell you is how dangerous a fire can be if you are not aware of its capability to spread and grow rapidly. Fires can be very dangerous and harmful. It is important to education each other as much as possibe to help prevent injries or deadly accidents. There are four stages that happen in every fire. Those stages are Incipient, Growth, Fully Developed, and Decay. Each stage plays a role in every fire. Understanding each stage, and how to handle or prevent it is critical in becoming in control of a fire. Flameovers and backdrafts are not consider stages, but also are definitely factors of a fire. These factors sometimes can be prevented. Some methods of prevention are taugh at fire academies, or fire schools, to new firefighters, and are constistly being developed. Incipient, also know as the "ignition" stage, is the first stage of a fire. In this stage smoke may began before the fire actually flames up. This is the stage where heat, oxygen, and a fuel source combine to ignite the fire. At this stage it can be controlled by a household fire extinguinsher. Growth is the second stage of a fire. With the initial flame used as a heat sourse, more flames flare up. Flaring up makes the size of the fire increase and the plume reaches the ceiling. In a room hot gases meet at the celing of the roomwhich cause all fuels in that room...

...Discuss the possible damage with short term and long-term complications of a firefighter inhaling heated air and in respiratory distress. Prioritize the necessary interventions to stabilize the patient. Then discuss an in-depth plan of care for recovery. Smoke inhalation is known as the leading cause of death due to fires. Firefighters are trained to recognize the dangerous short-term effects of smoke exposure caused by carbon monoxide and tiny particles absorbed into the lungs. The inhalation of heated air produces injury through several mechanisms, including thermal injury to the upper airway, irritation or chemical injury to the airways from soot, asphyxiation, and toxicity from carbon monoxide. In most cases firefighters can wear devices...

...During the unloading process at the HLF Polyurethane Manufacturing plants, a vapor return line ruptured causing a fire. This is due to a nearby welding operations at gave the vapor a point of ignition. The product that was being delivered to the manufacturing plant was toluene diisocyanate (TDI), and methylene diphenyl diisocyanate (MDI), which are products used in the production of polyurethane. Once the fire was recognized the alarm was sounded and the emergency response team was notified. The fire department was notified and the command area was establish and the emergency response plan was put into action by the incident commander. The emergency response team was not able to isolate the source, ultimately turning over the incident command and control of the fire to the fire department upon their arrival (Meyer, 2014). Two of the hazardous material that are used to manufacture polyurethane is toluene diisocyanate (TDI), and methylene diphenyl diisocyanate (MDI). Toluene diisocyanate contains a list of hazard that can be identified on the Safety Data Sheet, it is extremely toxic of inhaled, it is considered a carcinogen, and can cause skin reactions....

Whenever fire is been used in the firework fuse, you give enough enactment vitality to make strong concoction mixes stuffed inside the firecracker burns with oxygen in the air and change over themselves into different chemicals, discharging smoke and fume gases, for example, carbon dioxide, carbon monoxide, and nitrogen in the process. Also, whenever a firework bursts in the air, have you wonder, where does the color come from? Well the color of the firework is also behind of science. These colors come from metal compounds, also known as metal salts, packed inside....

...Uncontrolled blazes fueled by weather, wind, and dry underbrush, wildfires can burn acres of land—and consume everything in their paths—in mere minutes. On average, more than 100,000 wildfires, also called wildland fires or forest fires, clear 4 million to 5 million acres (1.6 million to 2 million hectares) of land in the U.S. every year. In recent years, wildfires have burned up to 9 million acres (3.6 million hectares) of land. A wildfire moves at speeds of up to 14 miles an hour (23 kilometers an hour), consuming everything—trees, brush, homes, even humans—in its path. HOW THEY ARE FORMED There are three conditions that need to be present in order for a wildfire to burn, which firefighters refer to as the fire triangle: fuel, oxygen, and...

...trained in firefighting, primarily to extinguish hazardous fires that threaten property and civilian or natural populations and to rescue people from dangerous situations, like collapsed or burning buildings. Luckily or unluckily, my cousin work as a firefighter. Since he became a firefighter, I never saw him at home having the dinner with us in Chinese New Year. He has to stand guard, and wait for the order if there something happen. We all know that the job as a firefighter is really dangerous. There is an explosion in my city as a result of the oil spilling. All of the firefighters including my cousin in my city went to the first rescue line to save lives and buildings. Everyone is in danger. Unfortunately, someone died in that accident. So that comes to problem: Should firefighters contribute their lives to save other’s lives or properties? My answer is no. It might because that I have someone who has the relationship with me in blood. So that I feel his life is important for me. I want him to protect his own life instead of saving others. How fire happens? It is clear that there are some place that can easily catch fire. Like some places near the forest or rainless. We know that if there is only a little fire in a tree, it will spread quickly. We learned some examples from Egan’s article. He argued that firefighters don’t have to die for people’s property and homeowners cannot blame firefighters. He shows the fire happens in Arizona where is really beautiful “ …...

...years is what they’ve predicted. Sure, when the days are 45 or higher in the mercury, then we’re all a little on edge. But when is the last time we’ve had high winds, low humidity and high temperatures? All in one day? It’s been years I reckon. Years since the perfect conditions. In the service we call this… a ‘crossover’. Happens rarely but when it does… yeesh. All the old blokes tell us about when they’ve had crossovers. You mention the word crossover to any firefighter and they will have a wealth of stories about fires with a hundred metre flame heights, flames running faster then you can sprint, the immense heat, and the sheer terror. Terror that gives seasoned firefighters nightmares. I’ve never witnessed a crossover before, unfortunately I joined a few years after Red Friday, the last known crossover to occur during a bushfire season. A few of the officers were at that fire; they’ve all left the brigade now. The officers will have lots to tell us about crossover fires, we just shrub them off, “yeah yeah”, we say, don’t worry, we’ve done our training. We’re prepared. All these old farts go on and on about this all the time, even though the boys, Jason and I included, are a bit young, we can handle it. A brigade full of young, fit and enthusiastic volunteers. Aged from 17 to 30, and then you got the few high officers that have been in the brigade 30 or 40 odd years. Although we haven’t seen a big season before, that doesn’t mean we can’t handle it. * * * Five weeks is how much...

...burning? - The fires were used to kill off parasites and unwanted pests. Example being the rattlesnake in the Southern states, and parasitic mistletoe that grew in California on the Oak. -Fires encouraged the growth of large tress that were used by natives to build canoes. - Fires cleared the forests, which meant that enemies of local tribes had little to no place to hide and would be easy to find. - Clearing the forests meant the growth of new vegetation on the forest floors, which attracted animals such as deer for hunting. 2) What human choices caused the firestorm that destroyed the town of Cloquet in 1918? - The European settlers had cleared out the old forest, but instead of clearing it out they just left the debris. The debris denied the vegetation the ability to grow in that area. The vegetation contained moisture that would've kept the fire from being as big as it was, possibly not even allowing the rail road spark to ignite the fire. As well as no one had used the traditional burning methods that the ecosystem had become a custom too with the natives that lived there before for several generations....

...Men were recruited from all over the United States to come to the West to fight the Big Blowup of 1910, but this hardly put a damper on the blazing fire. By the middle of July alone, there were over three thousand laborers employed to fight fires in Northwestern Montana and Northern Idaho alone (Silcox 1910, p. 635). These men worked hours trying to put the fire out, using any method imaginable in order to extinguish the flame; dirt, water, etcetera. However, what finally stopped the fire was trenches from 2 to 4 feet wide were dug down to mineral soil and all the inflammable brush and debris was thrown away from the fire in order to stop feeding the fire and put it out (Silcox 1910, p. 638). Digging trenches alone is a difficult task, but...
